TERA PUMP 55-Gallon Drum Water Pump — Manual Lever-Action, BPA-Free for Potable Water

TERA PUMP Emergency 55 Gallon Drum Water Pump is a manual, lever-action drum pump that dispenses up to 5.5 gallons per minute from 55-gallon barrels and is BPA-free for safe drinking water use.

This durable polyethylene and polypropylene pump is built to move a wide range of liquids—including drinking water, light oils, diesel, kerosene, and many common chemicals—without electricity. Designed to slide into standard 2-inch NPS drum bungs, the unit combines a 33.4-inch suction tube with a 47.2-inch corrugated discharge hose and a piston-action handle for fast, reliable transfer during emergencies, workshops, farms, or industrial sites. The vented cap offers simple flow control by tightening to create siphon suction or loosening to slow or stop discharge.

How fast will this pump empty a 55-gallon drum?

At full manual operation the pump transfers about 5.5 gallons per minute. Actual speed depends on how forcefully you operate the piston and the liquid’s viscosity; thinner liquids move closer to the maximum rate.

• Rated delivery: up to 5.5 gallons per minute
• Hand-powered piston action—no electricity required
• Flow can be reduced or stopped via the air vent cap

How do I install and control flow from a 55-gallon drum?

Installation is simple: insert the 33.4-inch suction tube into the drum, then fit the included 2-inch NPS bung adapter at the desired height before securing the vented cap. The corrugated 47.2-inch discharge hose includes a nozzle holder and can be positioned for convenient pouring.
